Erion or Two brothers?
IMO, Two Bros looks and sounds better.Additional benefits to carbon fiber besides looks and mabey minimal weight savings but nothing noticable. The two guys that started Erion and Two Bros are brothers FYI
everyone i have heard when asked about the bes sounding pipe.....80% all say two bros. they say its very deep, then gets loud in the upper revs.....sounds purrfect to me.
two bros between 4.5K and 5K is the best deepest sound and thats highway cruising (60mph), everything below that is deep aswell but not AS deep as between those particular rpms. once you get above 5K rpms it gets louder, but not as deep of a sound (NOT high pitched wining either!). then once you get to the double digit rpms it gets a LOUD deep sound .
